Plain English Summary

Background and study aims
Non-alcoholic fatty liver disease (NAFLD) is a term used to describe a range of conditions caused by a build-up of fat within the liver. A normal liver should have no, or very little, fat. Simple fatty liver, which is harmless, is common in people who are overweight or obese. Over time, however, simple fatty liver can develop into non-alcoholic steatohepatitis (NASH) where the liver becomes inflamed. At this stage, people might experience a dull ache in their abdomen but it often has no symptoms. Persistent inflammation of the liver can develop into fibrosis where fibrous scar tissue develops around liver cells and blood vessels. The liver is still able to function normally at this stage. The final stages are cirrhosis and end-stage liver disease, in which the scarring is so extensive that the liver shrinks, becomes lumpy and begins not to function normally. Recent information has shown that exercise may help people with fatty liver. It may help reduce the amount of fat in the liver by increasing the ability of the body to burn fat and increasing the sensitivity of the body to food. Evidence also suggests that exercise may help to reduce active injury and inflammation in the liver. We want to show the effect of exercise on the levels of fat, injury and inflammation in the liver and the sensitivity of the body to food. Understanding the relationship between exercise and liver injury is important in gaining acceptance of exercise in the management of fatty liver and avoiding excess weight gain.

Who can participate?
Adults aged between 18-75 with a fatty liver, drink a moderate about of alcohol, does not do a lot of exercise and are at a stable weight.

What does the study involve?
Participants are randomly allocated into one of two groups. Those in group 1 (intervention group) undergo 12 weeks of supervised exercise. Those in group 2 (control group) do not attend any exercise sessions. Both groups of participants go to the research facility 5 times throughout the 12 week exercise period, in which the amount of fat in the liver is measured (using a magnetic resonance scanner) and blood tests are taken to check for liver injury and inflammation.

What are the possible benefits and risks of participating?
Being more physically active may be beneficial to the level of fat, injury and inflammation in the liver and if sustained after the study, may help in preventing other complications such as heart disease and diabetes. Participants in the intervention group have supervised exercise sessions (like a personal trainer) which will teach them about their body, show them how to exercise correctly and help them become more physically fit. Participants in the control group are given the opportunity to have an individualised exercise programme. There are minimal risks to taking part in the exercise programme.

Study information

Scientific title

The effect of exercise on liver lipid in people with fatty liver with moderate alcohol intake


Study hypothesis

To characterise the effects of resistance exercise upon factors which influence the development and progression of fatty liver in people who regularly consume a moderate amount of alcohol.
1. The primary aim is to observe whether performing a programme of resistance exercise reduces liver fat in people diagnosed with fatty liver in the absence of any changes in alcohol consumption.
2. The secondary aims are to understand the influence of resistance exercise upon factors which influence the development and progression of fatty liver to steatohepatitis: insulin sensitivity, lipid oxidation, regional adiposity, and cytokine production. In combination, these observations will provide the first report of resistance exercise upon fatty liver with continued alcohol intake and its underlying mechanisms. These novel observations will lay the foundation for a larger study to define the effectiveness of resistance exercise as a part of the clinical care of people with fatty liver who continue to drink alcohol.

Participant inclusion criteria

1) Fatty liver; this is the study group.
2) Moderate alcohol consumption (18-42units/ week for men; 11-28units/week for women).
3) Sedentary; we are looking at the effect of increased exercise.
4) The person's weight needs to be stable prior to entering the study as we are interested in the independent effect of exercise.
5) Aged over 18 years.
6) Understanding of English (as without this supervised gym visits will not be possible).; Target Gender: Male & Female; Upper Age Limit 75 years ; Lower Age Limit 18 years
